python - django的模板预加载

Question

就是如： return render(request, 'index.html', {'lists':lists})
假设我lists的数据处理比较多麻烦，所以渲染打开页面的时候可能较长，
那怎么让他渲染好之前，先弄个预加载图片什么之类的。
就是不要停在空白太长时间。谢谢

Answer 1

render is returned to the front-end after the back-end renders it
It is divided into two parts: data and pictures
1. The data is asynchronous and processed by ajax, that is, your back-end does not render the data and obtains the data through asynchronous calling interfaces
2. Picture preloading, please refer to: http://www.cnblogs.com/haoyij...
